The scheme of electric insoles with electric heating. Heated insoles - how to make your own hands and features of use in extreme conditions. Why do hunters need

Prepare the sleigh in the summer - says the Slavic proverb. If sleds are not needed, then warm shoes are what are in demand in winter: both by outdoor workers, and by athletes in winter sports, and simply by pedestrians standing at frosty stops.

But shoes are not always warm. Additional insoles will not help, and when you put on several socks. What is the way out: endure the frost again or come up with something, or something invented by someone to try?

Insoles-ships

Global firms also offer a way out, but at overpriced, from the point of view of Russians, prices for their products for warming up feet in winter shoes. To roughly understand what they are, just go to sites that sell heated insoles and look at their photos.

Insoles filled with electric heating elements for long-term use or one-time use are inserted into boots or boots. They were originally, most likely, developed using space technology, and then went to ordinary consumers in countries with a cold winter climate, including Russia. So it was with the famous "Velcro", which today is not used anywhere in everyday life.

The craftsmen, who will tell you what heated insoles are, did not stay aside, as always. They themselves have contributed to the electric heating of the legs. Let's talk more about this, it is possible that many use the recommendations for the independent manufacture of shoe heat convectors.

What to make a "stove" for the feet?

An insole or orthosis is inserted into the shoe for a number of functions. And more for medicinal purposes - from pain in the foot and joints with arthrosis and injuries, correction. About the function of heat preservation - not a word.

Only in the comments there are messages about how to make just warm insoles yourself - from a felt mat, foil penofol and building isolon. We will offer ideas on how to make heated insoles. Anyone can tackle this challenge.

Below is a step-by-step instruction on how to make insoles with your own hands. We will show on the example of insoles with autonomous heating from a mini-battery (accumulator) with adjustable temperature.

A number of factors must be taken into account. First: choose insoles with a base that does not conduct heat well - so that they do not “go away” into the sole, but warm the legs. According to their characteristics, insoles made of felt 0.5 cm thick are suitable.

The second factor: experiments have shown that the most freezing zone of the feet in the cold is the toes. So they need to be heated, and the blood heated in them will insulate the rest.

And this will save on energy costs, because the electric current is generated not by a powerful car battery, but by the one that powers smartphones and tablets. That is, the battery should fit in the pocket of a person whose feet are heated by insoles. The best insoles with heating on charging.

The heating element of a homemade device is a wire with a predominance of two types of metal - nickel and chromium. It is wound with a spiral for more power, it serves as a heating element for home electric stoves. For insoles, ten times shorter (48 cm) wire is enough and much thinner (0.3 mm). It can be taken from any non-working 300 watt heater. Sometimes you can buy at an electrical store for 20 rubles.

Buy a voltage regulator from four volts and above in a Chinese store. If you don’t want to bother with homemade products, buy factory-made electric insoles with charging in the same market.

But the master himself assembled the convector on the insoles

I laid a heating thread across the insole so that when walking with bends of the sole, the wires would not move. The entire length of nichrome is sewn to the base.

There is room for a second layer of heating element. It will be mounted on a leather base, and it transfers heat well to the feet. At the same time, little energy is lost, and the skin does not warp from the heating of the elements. The leather insole is sewn to the bottom - the seams will pass between the nichrome threads.

Two nichrome contacts are removed from the insole, two stranded copper wires up to one and a half meters long each (plus and minus the battery) are soldered to them.

Note!

"Power station" for insoles

The main element is a nickel-metal hydride battery at 7.2 volts, with a current of 5000 milliamps per hour. Without recharging from the mains, the battery will warm your feet from 5 to 11 hours of continuous operation. The heating of shoes depends on the named parameters - voltage and current.

Better than a 12 volt battery. The maximum warm-up is 60 degrees, but the adjustment keeps any comfortable, and not with overheating. It is worse than frost - blood pressure will rise in people over 50.

Factory heaters

ThermaCell offers insoles weighing 0.5 kg each for almost 16 thousand rubles. A strange price, because through the online store they will deliver the same devices much cheaper. It is not clear why the price is going up. Insoles - under the 46th size - heat up only up to five hours. Then recharge the battery.

The WarmSpa kit has a budget price at all - through Yandex Market - 3750, on Aliexpress - 1450 rubles. But with two batteries, for 3-6 hours of work. There is a color heating indicator, convenient to adjust the temperature. The downside is a thick insole - up to half a centimeter.

There are Russian-made insoles with replaceable batteries in the sale - they cost about 1200 rubles. Warms up fingers well. Batteries can be changed without removing the insoles. Severe frost reduces the voltage and current of the batteries.

Note!

Blazewear insoles are heated by a pair of AA lithium batteries. The compartment with them is attached to the leg with Velcro.

Heated insoles from "Heat Generator". Chemical heating - up to six hours. The elements are bioecological. The insoles are light and comfortable to wear. The cost is simply ridiculous - less than 300 rubles.

Note!

Winter can be very cold and harsh. This is especially true of places close to the Arctic Circle. Despite this, everyone experiences a cold month or a few days from time to time. At this time, the legs can become very cold, and there it is not far from illness. Heated insoles can help you cope with the cold.

Who needs insoles?

In addition to cold days and very harsh conditions for life, there is also a simple everyday life. Such a device will not be superfluous for people who simply have cold feet. They are mandatory for people who are on the street for a long time, whether for work or vocation. I am now talking about open market sellers, for whom the working day means being in different conditions, especially in winter.

In addition, battery-powered heated insoles can help fishermen, for whom this is, if not a mandatory attribute, then desirable and recommended. Hunters also belong to this category, along with people who also work in nature, regardless of the time of year. It can be farmers, builders, drivers.

How the insoles work

The overall design always consists of several unchanging parts. We are talking about the insole itself, the heating element, which is usually a thin conductor thread, and the power source.

You probably already guessed that heated insoles can be made by hand. To do this, you need to choose the components yourself. There may be some improvements that are more dependent on the craftsman who makes the insoles.

When choosing a conductor, be sure to consider the resistance, you can not make mistakes with it. Calculations play a very important role while working on insoles.

A simple system, a photo of which can be easily found on the Internet, provides for several power sources. Usually they use simple batteries, which are installed from three pieces. Why? It's all about the several modes of operation of such insoles.

In the first, the batteries will work at 2/3 of their capacity. This mode provides for the constant maintenance of the insoles in a warm state. The second uses the full power of the power source, while the insoles heat up much more and become hot.

It is envisaged that in this mode they should not cause burns and severe discomfort. This is needed more for very low temperatures. Both of these modes should be tested several times before using the insoles personally.

There is no need to save time on this process, because faulty insoles can cause serious damage to your feet.

Materials for making insoles

Nichrome is well suited for a heat conductor. A thin thread of 2 tenths of a millimeter will be enough, which will reach 25-30 centimeters. Having connected it to the power system, it is worth checking the conductor. This is necessary in order to find out how homemade heated insoles will behave.

To do this, take a not very thick cloth, put the thread connected to the batteries into this cloth, and take it tightly in your hand. The temperature should be high enough to heat the hand, but not too high so as not to burn it. Based on the results obtained, we adjust the temperature.

We return to the power source. As mentioned earlier, simple AA batteries will do. Two of these batteries can provide you with a charge of just over 250 milliamp hours. At the same time, three batteries contain up to 400 milliamp hours. Next, we select the required volume of the battery, on which the operating time of the insoles in the heating mode will depend.

More situational components will tell you the instructions on how to make heated insoles at home. These include additional conductors that will connect the nichrome thread and other consumables.

Manufacturing process

First you need to connect a nichrome thread with a wire that will lead to the batteries. To do this, you will need contact sleeves. The cable must be at least 45 centimeters longer than necessary to reach the insole.

How where the thread will be laid - everyone decides for himself. Most often, it is concentrated in the front of the insole, which freezes the most.

Next, you will need to work with a simple needle and thread. Yes, the heating element needs to be fixed, and almost nothing is better than a simple thread for this. At the same time, the other end of the wire will receive a 3.5mm plug that will connect to the battery system.

Next comes the power supply. it will be attached to the leg, and therefore it needs a body. it is selected by batteries with one condition - no matter how many you take, the case must hold one more. You need this for a controller and a connector that will work with a mini jack.

Having finished working with a soldering iron, you will need to fix the whole thing, for which you will need hot glue. To keep the batteries from falling out, take two simple rubber bands and put them on the top and bottom of the device.

Everything that we have now managed to somehow fix on the leg. A simple Velcro tape works well for this. It will need holes in the body that will need to be drilled. Then we connect the two parts with threads and the device is ready for use.

This is by the form of ordinary socks, which are made of a special material, with built-in heating elements. Designed to keep your feet warm in wet and cold seasons. Their feet do not sweat. For each type, the device is different, but the principle of operation is the same, they heat and create comfortable warmth.

• On batteries. They have a fairly low price, due to the change of batteries. The choice is quite large in color. For lovers of just skiing or relaxing, this option is suitable. They work up to five hours maximum. This time is enough for simple walks.
• on a battery device. Ideal and practical. Expensive price. Comfortable, standing model. The battery can be charged with a 220W charger, as required. Suitable for extreme sports. Work more than 6 hours, then recharge is required.

Pay special attention to the choice of insoles for socks. There should be a sufficiently dense material, this will make it possible to use for a long time. There are quite a few options for insoles on the consumer market.

How to choose the right socks heated

• In order to choose the right heated socks, first decide for what purpose they are needed.
• Next, decide on the type of models.
• Find out the principles of operation and operation of this model.
• Pay attention to the appearance, attaching parts: wires, batteries, batteries.
• Check out all the details of this product.
• Ask for a demonstration of these socks.
• Check the correct operation.
• Specify the reasons for the return of this item, this is in case something does not suit you. Or there will be disappointment.
• Consider the price. Perhaps in a nearby store or on the Internet, prices are much lower. Well, if there are no problems with this, then feel free to buy and use it.
• Buy products by size, because there is no need to do with a large size.
• Don't forget to take your receipt with your purchase.

Who makes heated socks

• Blazewear is made from merino wool.
• Firm Peltu Heat, produces high socks.
• Firm "Fahrenheit".

How heated socks work

There is a pocket on the top of the product. It is needed for the carbon plate.

ATTENTION: built-in element, emits infrared heat. Further, this heat is distributed throughout the foot, including the toes. Feet at low temperatures do not freeze, but do not sweat. This gives maximum comfort, is a long time on the street.

REFERENCE: Ideal for skiing and sports. Allows you not to feel the cold for a long time, for those whose work is connected with the street.

The temperature regime is up to 45 degrees Celsius.

REFERENCE: But not all models.

These heated socks work either with a rechargeable battery or with built-in batteries. From the carbon, durable plate, 2 wires depart and are attached to the batteries. The assembly scheme itself is quite small in size and therefore, when put on, the movement does not bring any discomfort.

Batteries are attached to the leg itself with a belt. And in the second option: They can be folded into a small special pocket, the developers came up with this for convenience. Each sock has a control unit with a switch. The work is done offline. If the sock gets wet for some reason, then nothing terrible will happen, only the thermal regime may decrease a little, literally by a few degrees.

How to take care of heated socks

So that socks do not lose their quality, you need to properly care for them:

• Wash. Yes, they do not absorb odors, do not dye, but the fibers are still clogged with dirt particles. You need to wash either in a washing machine with a delicate wash up to 35 degrees, or by hand. Water temperature up to 40 degrees, not higher.

IMPORTANT: Do not use bleaching powders and products.

• When hand washing, use baby soap.

REFERENCE: You can't take it to the dry cleaners. It is impossible to squeeze and twist, because there will be a violation of the fibers. You can only shake off your hands and nothing more.

• Drying. Dry naturally. Heating appliances, electric batteries are contraindicated. The fabric will lose its properties, which simply cannot be restored. Ironing is not possible. Lay on a flat surface, straightening occurs independently without physical effort.

ATTENTION: Do not dry in the washing machine.

If you follow all the rules for caring for this product, then it will last more than one year.

ATTENTION: Take care of yourself, carefully study the instructions.

Pros and cons of heated socks

Of the minuses: Batteries need to be charged. Takes a day. Short wires and therefore have to put on for a long time.

ATTENTION: They released extension cords, but not for all models.

Socks with a heating function can easily be called one of the best inventions of our time.

In the RedLaika online store you can buy battery-powered or rechargeable heated socks!

Foot warmer

Socks with batteries or rechargeable batteries provide warmth for a long time. For this, infrared radiation modules are located in them, due to which a normal temperature and blood supply are maintained. The plastic case is placed in a special pocket located at the top of the socks.

The lower extremities are heated for a period of 8 to 16 hours, maintaining a comfortable temperature and eliminating the risk of hypothermia dangerous to health.

Principle of operation

The warming socks are made of a specialized material that adapts to the curves of the foot and lower leg, and the warmth is maintained with the help of heating elements. Models of socks offered in our catalog consist of natural threads, which become more plastic due to a small percentage of acrylic or spandex.

The pocket allows you to place a carbon plate or batteries, while they do not interfere with walking. Heat is efficiently distributed and warms the entire foot, heating elements are located in the areas of the foot that are the first to cool. Heating to a temperature of about 45 degrees provides the desired level of heat.

Do-it-yourself heated insoles will be a good find for people who, due to circumstances, are forced to be outside for a long time in winter. This simple device will help keep your feet warm when fishing, hunting, hiking, market sellers, etc. In addition to the cold season, insoles will come in handy in spring and even in summer, in rainy weather.

One of the most sensitive parts of the body to cold is the feet. If they freeze, the whole body begins to freeze, which gives us great discomfort, not to mention the risk of catching a cold. Heated insoles will help keep you warm in extreme cold.

There is nothing tricky about the device of heated insoles. Depending on the type of product, the principle of operation will also differ. Products are made of several layers:

• the bottom layer is an insulating material in the lower part, which retains heat well and does not allow moisture to pass through;
• next comes a pressure sensor, a connector for a charger, a battery and electronic elements, a heating element is located in the fingers or along the entire foot;
• penultimate layer - polyurethane absorbing and synthetic insulating layers;
• the last layer is a non-fabric lining.

High-quality heated insoles should evenly distribute heat over the entire foot, repeat its shape. It is desirable that in the area of ​​\u200b\u200bthe fingers there was perforation. Thanks to her, they will warm up faster.

The insoles often have indicators of the heating mode. Can run on regular or rechargeable batteries. The design of the products is made in such a way that they are very easy to put into shoes, and several size options allow you to choose individual insoles for each.

Types of heated insoles

There are three types of "warm" insoles: rechargeable, battery-operated and chemical. The first two types have a heating element in their design, they are divided into wired and wireless.

Wired

The insoles have an external battery and a heating element inside the structure itself. Even if you have used such a thing for the first time, you will not see discomfort in wearing, the leg quickly gets used to it.

The battery and the heating element are interconnected by a wire of 40-60 cm. The batteries themselves are attached to the lower leg, and the temperature regime is changed using the control panel. Despite the fact that the main element is outside, there is no risk of injury. All wires that are energized are hidden in a plastic, tightly closed box.

Wired insoles can work up to a maximum of 12 hours, which is enough to spend the required amount of time in the cold or in cold water. Heated insoles on the battery can be made with your own hands, it will turn out no worse than the purchased option.

Wireless

In such insoles, the batteries are placed inside the product, most often in the heel area. The heating element is located in the toes, because. they are the first to freeze. Specially selected materials allow you to keep heat inside the insole: artificial plastic and natural rubber.

If you prefer wireless heated insoles, then choose your size immediately, taking into account the height, because. there is no way to “customize” the product for yourself. The operating time of the insoles is also rather big - up to 11 hours, with 4 hours to a full charge. Some models are equipped with a remote control. This allows you to turn them off when you enter the room.

Chemical

Another type of heated insoles are chemical insoles. Mostly disposable. Sold in hermetically sealed bags. To make them work, you need to shake or rub each insole with your palms after printing. This will start a chemical reaction. After the insoles have begun to heat up, they are put into shoes. There are models that can be glued to socks with a self-adhesive tape located on one side.

The heating of the insole occurs due to the oxidation of iron. To avoid burns, manufacturers add chloride and sodium salt, which reduce the oxidation process. Sawdust or charcoal is also added to some products to eliminate odor and moisture.

The work of chemical insoles is designed for 6-7 hours. It heats up no more than 45 0 C. For a short walk, this is quite enough.

Advantages and disadvantages of wireless insoles

Heated insoles have both advantages and disadvantages. Product benefits include:

• keep your feet warm even in severe frosts;
• wireless insoles can be selected according to size;
• in products of a chemical type there are children's sizes;
• adjustment of temperature and heating modes;
• fast charging from a conventional network;
• comfortable to wear;
• can be turned off when entering the building.

The disadvantages of insoles are as follows:

• not all budget models are able to retain heat for a long time;
• high heel position in wireless insoles gives a feeling as if you are on a heel;
• in akb models, the battery has to be hooked on the leg;
• there is a risk of breakage or wire breakage at the most inopportune moment.

After weighing all the pros and cons, you yourself decide on the purchase of "warm" insoles. If you don’t want to spend money in vain, you can make heated insoles for fishing or just walking with your own hands from improvised materials.

Instructions for making homemade heated insoles with your own hands

How to make heated insoles with your own hands? Everything is very simple. For the manufacture of heated insoles, it is important to pay attention to the selection of materials so that heat loss at the bottom is minimal and heat transfer to the feet is maximum. You will need materials and tools such as:

• a pair of felt insoles;
• material for the front layer of the insole (you can take genuine leather, jeans, leatherette);
• nichrome wire about 60-70 cm;
• battery case (4 compartments);
• accumulators;
• switch for 2 or 3 modes;
• wire MGTF 4 m;
• crimp sleeve S = 0.2 mm 2 4 pcs;
• set of socket and plug 2 pcs;
• heat-resistant tube 1.5-2 m;
• strips of woven Velcro;
• pliers.

The manufacturing process at home consists of simple steps that even a non-professional can perform.

1. With the help of crimp sleeves, the MGTF wire is attached to the nichrome wire. First, the sleeve is put on the wire, the end of which is then inserted into the cleaned wire. The joint is closed with a sleeve, which is then crimped. Outside the insole, the wire should protrude no less than 50 cm, for convenient attachment to the leg. The wire on the insole is arranged in random order, as you like. You can attach it with thread and a needle.
2. A headphone plug is soldered to the free end of the wire to connect the insoles for recharging. A hanging stranded wire is sewn on the side of the insole to about the middle.
3. The upper part of the insole is cut out of a piece of leather and applied to a felt base with wire.
4. Now the battery is being set up. A plug socket is mounted in one of the four compartments in the battery case.
5. Velcro is attached to the back of the battery compartment. Two batteries are inserted from the front side. In this case, the heating temperature will be no more than 35 0 C. If this is not enough, you can insert a third battery.

Thus, in just an hour you can make heated insoles on a battery with your own hands and feel comfortable in any weather.

The nuances of making heated insoles for fishing

Homemade heated insoles for use in fishing must be made taking into account the surrounding conditions. If there is a risk that water will get into the shoes, the material for the insoles must be waterproof. All wires must be carefully hidden inside. It is better to make insoles wireless so as not to wet the batteries on the foot. Switching modes should also be convenient. Better if it is a remote control. Then, even while wading waist-deep in water, you will be able to regulate the heating temperature.

Features of the operation of heated insoles

Using homemade products is more than easy. The main thing in the product is that it should be the size of your shoes, otherwise it will fidget inside. Follow the rules for using insoles so that they serve you for a long time:

• the integrity of the protective cover must not be violated;
• wet products;
• bend insoles;
• stretch, press down the wire;
• dry as soon as you get home.

Charge wireless insoles in time so that you don’t suddenly be left without a heating pad on the street.
